Yeah, I know that, but the picture is not overburned, and ACR is able to recover it.

Having trouble with 20MP files as it is
Yeah the K1 files are quite demanding. My MacBook Air does the job, slowly, but it works!
Originally posted by Homo_erectus the only raw processor that handles highlight recovery in a less manageable (and successful) way is Silkypix
I think Silkypix / PDCU could be a study case in design schools to provide a concrete example of what should not be done ^^.
Originally posted by shardulm I have come to a point where I have started to underexpose shots that will result in clipping. I found that it is much possible and less time consuming to recover details from a pitch dark looking pixel than taming a burnt pixel. Does anyone here feel the same way?
Yes I also underexpose in order to recover in post, as underexposed areas are a lot easier to recover.
Originally posted by Trickortreat Thing is - people think that they can recover blown highlights. You cant. If you blow out your higlights you have no data to work with. There is no colour information for those regions of your file. Highlight recovery is a tool that works when you dial up yoi ev compensation and want to pull your existing highlights in a more appropriate luminance range. Blown highlights have no data and best programs can do is aproximating. Some do it better than others but at the end of the day you just get wrong colour blotches.
I know that, and as I said, the picture is definitely not burnt.
Originally posted by todd There are different "methods" for highlight recovery in RT with the "Highlight Reconstruction" options, with "blend" being most often the best choice, but sometimes the wrong choice. "Color propagation" sometimes works amazingly well. Then there are "Highlight Compression" sliders in the exposure section, and the Highlights slider further down in the Shadows/Highlights section... It's definitely not a one slider fits all situation. The highlights options in RT can definitely be overused and result in various undesireable outcomes fme, especially as different tools in RT are brought into use too. I usually use a combination of the tools mentioned and not aggressively.
Originally posted by house I find the highlight recovery of Rawtherapee to be great. Push it to far and you get artifacts though, which is expected.
Under the Exposure tab use the Exposure module and dial back the exposure a bit. I find it better to lift the image using other tools if required. Then click the Highlights recovery toolbox and select color propagation. I find color propagation works for most images but it can result in strange effects if pushed to far. Then pull the Highlight compression until satisfied.
Color propagation highlight recovery is almost magic.
Thanks, that's more or less what I tried. Still, ACR does a lot better job (better result, and a so easy to use!)
Originally posted by wildman Better? If so I just ran it through PS in the usual way like any other file
Yes better, but I'd like to be able to get that in RT directly.
Originally posted by The Squirrel Mafia I'm going to guess that your RawTherapee is set to the Default processing profile. Try using the Neutral processing profile. If all you're going to do is open & convert a pixel shifted image, then the Neutral processing profile will leave it as it was caught on the sensor with no adjustments whatsoever. Then you go to the Raw tab, set the Demosaicing setting to Pixel Shift, do other correction settings if necessary, & export the image. After that, you can use ACR to process your image
As others said, when you do that, you say bye bye to the awesome dynamic range of the K1, quite a shame... A solution could be to export several tiffs at different exposure compensations to create a "fake HDR", in order to preserve some of the dynamic, but it's very time consuming!
So to sum up, seems we have to live with that, and hope that Adobe implements motion correction in Lightroom / ACR (which is not planned at the moment, from what I red a while ago). RT does a better job in pixel shift than ACR (not a lot, but a bit), it's really a shame that the highlight recovering doesn't match ACR's :/
Thanks anyway for your answers
! You deserved a nice sunset (K1, pixel shifted HDR post-processed in ACR. You can see some artefacts in the bottom right, but that's a lot better than what I get by exporting each shot to a tiff before creating the HDR) :
